Examples of "acryloid"
GD can be thickened for use as a chemical spray using an
copolymer. It can also be deployed as a binary chemical weapon; its precursor chemicals are methylphosphonyl difluoride and a mixture of pinacolyl alcohol and an amine.
Polished silver is sometimes lacquered to protect against tarnish and to prevent over-polishing. There are different types of resins that are used such as
B-72 and Incralac. If silver pieces are being displayed in the open, such as in a house or museum exhibit case, it is difficult to prevent corrosion from air exposure. A surface coating will prevent or slow tarnishing and is a service done by professionals or conservator. One of the most used coatings is Agateen.
The first step in the physical filling is creating a backing that is applied to bridge the area of loss and the fill material. The "most commonly used materials for backings are inert fabrics coupled with either resins, starches, or cellulose ethers with evaporative solvents, or resins or systems requiring the use of a heat-seal process." The next step is creating a template of the area of loss. That template is then transferred to the fur and cut to size. The patch should be applied to the object with "
F-10 in acetone" by applying the adhesive directly to a substrate inserted in the hole and placed the edged of the fill directly adjacent sides of the existing fur. The full should then be cut and textured to match the surrounding fur. As with all conservation efforts, it should be fully documented and reversible.
Acids can be used to learn more about fossil eggs. Diluted acetic acid or EDTA can be used to expose the microstructure of shell that has been damaged by weathering. Acids are also used to extract embryo skeletons from the egg encasing them. Even fossilized soft tissue like muscle and cartilage as well as fat globules from the original egg yolk can be uncovered using this method. Amateur paleontologist Terry Manning has been credited with groundbreaking work developing this technique. First, the paleontologist must submerge the egg in a very dilute phosphoric acid bath. Since the acid solution can penetrate the egg, every few days the specimen must be soaked in distilled water to prevent the acid from damaging the embryo before it is even exposed. If embryonic fossil bone is revealed after drying from the water bath, the exposed fossils must be delicately cleaned with fine instruments like needles and paint brushes. The exposed bone is then coated with plastic preservatives like
B67, Paraloid B72, or Vinac B15 to protect it from the acid when submerged for another round. The complete process can take months before the whole embryo is revealed. Even then only about 20% of the eggs subjected to the process reveal any embryo fossils at all.
Another example of a treatment often performed by conservators is the consolidation of the pole's surface which can be performed in a variety of methods. In a paper presented at the 42nd annual American Institute of Conservation of Historic and Artistic Works discusses the utilization of Butvar B-98 and Paraloid B-72 as the selected adhesives for consolidating splinters and detached fragments. Another method for consolidating wood is with the use of epoxy. Epoxy is a method for adhering smaller fragments of wood or larger wood fragments such as wings, beaks or fins of animals. "Epoxy repairs are difficult to reverse without harming the wood, and skill and experience are required to select and apply epoxies, bulking agents and tinting products". Materials used to consolidate paint surfaces are
B-72 in acetone which is applied with a brush. Last, a necessary and common treatment is an insect treatment. A product often used by conservators for infestation is Bora-care. This product is ingested by insects and impedes their ability to digest and thus starves them to death.
